A Duplex 2205 lateral is a fitting with a 45° branch, made from Duplex 2205 to ASTM A815 WPS31803 / WPS32205. Laterals bring in a branch at 45°, reducing turbulence and pressure drop compared to a tee. Common in drainage, slurry and process lines.

FOB / CIF · Nhava Sheva (JNPT), MumbaiDuplex 2205 Lateral — questions buyers ask
When is a lateral better than a tee?
Where lower turbulence matters — slurries, solids and gravity drainage.
Which standard covers Duplex 2205 laterals?
The material is ASTM A815 WPS31803 / WPS32205; dimensions follow MSS SP-43 / manufacturer standard. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Duplex 2205 lateral?
The alloy price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
Can you supply Duplex 2205 laterals to NACE MR0175?
Yes. Duplex 2205 is listed in NACE MR0175 / ISO 15156-3 within its limits; state NACE compliance on the order and it is confirmed on the certificate.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
